See what you can build with it in Hypamoon, how it signs in, and the sources we checked." url: https://hypamoon.com/connect-to/smartsheet --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Smartsheet Work and projects # Connect Smartsheet to Hypamoon Yes. Smartsheet has a public, versioned API and you create the key yourself, so your chat can write the adapter. Open ## The check Three questions about the API of Smartsheet, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://developers.smartsheet.com/api/smartsheet/introduction) **A key you create yourself**\ **Yes.** Generate an API access token yourself under Apps and Integrations in the Smartsheet UI. [developers.smartsheet.com](https://developers.smartsheet.com/api/smartsheet/guides/getting-started) **Versions or a changelog**\ **Yes.** API version 2.0 in the base URL, a dated changelog and a deprecation process. [developers.smartsheet.com](https://developers.smartsheet.com/api/smartsheet/changelog) **How it signs in**\ API access token as a Bearer token; OAuth 2.0 for apps used by other people. **Webhooks**\ **Yes.** It can tell your app when something changes. [developers.smartsheet.com](https://developers.smartsheet.com/api/smartsheet/guides/webhooks) **Hosting**\ Cloud **Condition**\ Generating an API access token needs a Business, Enterprise or Advanced Work Management plan. ## What you can build Add a row to a sheet from your chat or a web form, look up rows, and get a message when a sheet changes. Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow. - Tokens for Smartsheet, Smartsheet Regions (EU) and Smartsheet Gov are separate and use different base URLs. ## Try it in your chat Fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Smartsheet. API docs: https://developers.smartsheet.com/api/smartsheet/introduction. Read: \[what\]. Write: \[what, or nothing\].

Ask the chat to check its API. The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found. Say this in your chat > Check if \[software\] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog.
